Pouring spouts, Inc., Fortland, Drop, a corporation of Oregon Application January 8, 1932, Serial No. 585,503 Renewed January I, 1935 4 Claims. (Cl. 221-11) My invention is intended for use in conjunction with containers within which materials may be stored and from which they may be poured, or disposed of at the will of the user. a

My invention is primarily made of metal, fibre, paper, or any other suitable material, or a combination of all of them.

The invention primarily comprises a pouring spout attached to the container either during the process of manufacturing the container or at any other time thereafter. The spout may be removed from an empty container and applied to a new one of like or similar character.

An object of my invention consists in a method of attaching my device to the blank material from which the container is to be made so that it may be used to facilitate the filling of the container with the product to be presented to the market. Thereafter a sealing jacket is applied to thereby seal my attachment to the .container and to seal the opening formed therein in manufacturing or applying my device.

With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinafter shown with reference to the drawings which accompany and form a part of this specification.

In the drawings:

Fig. 11 is an inverted, perspective, plan view, of the pouring spout illustrated in Fig. 10.

Fig. 12 is a sectional, side, view, of the pouring spout as illustrated in Fig. 7, the same being taken on line l2l2.of Fig. 7, looking in the direction 15 indicated.

Fig. 13 is a fragmentary, sectional, side view of the pouring spout, illustrating a locking lip in clamping position when upon the container to which the same is attached.

Like reference characters refer to like parts throughout the several views.

My device is primarily adapted for being placed upon containers in which granulated, or other products are to be stored and from which the same are to be poured in portions, as required.

The device is adapted for being placed upon the container either during the process of its manufacture, or for being attached to the container at the point of use of the container. If 3 the device is to be attached to the container during the process of its manufacture, the same would be made as illustrated in Figs. 2, 4, 5 and 6.

The blank from which the container is to be made is illustrated at l and a cut-out portion 2 is formed within the blank that creates an opening 3 within the container when the blank of the container has been folded. When so made the body element 4 may be attached thereto and the container 5 be then filled by the placing of the same under the hopper 6, the lower end of which is placed in registry with the opening 3 and the container is filled with the materials to the full capacity of the container. Thereafter the spout is hinged down as illustrated in Fig. 1 and the cover jacket I is then placed upon the container.

The pouring spout comprises a body element that is formed of a top 8 and side walls 9 and Ill. The top portion 8 is cut out, as illustrated at H, sumciently to form an opening through the top, that is adapted for being placed in registry with the opening 3 formed at the corner of the container. Locking tongues I2 are punched from the respective side walls. and are forced inwardly sufficiently to cause the same to grasp the side walls of the container and to be held firmly thereto. Locking tongues l3 are formed from the side wall In. Openings are formed within the side wall 9 through which the locking tongues may be made to pass, thereafter the locking tongues are bent over sufficiently to secure the side walls 9 and I0 rigidly together.

A locking flange I4 is formed from the side wall 9 to further stiffen the assembly. The pouring spout is formed by a side wall l5 and a closure plate l6, both of which are united along their abutting edges, and hinged to the top member 8 by any suitable means as through the use of hinge pin II. A slit I8 is formed within the top 8 and the outer peripheral edge of the side wall I5 is adapted for engaging the arcuate rim IQ of the side wall IS, the purpose and object of which are to maintain the side wall IS in intimate engagement with the edge 28 of the top member 8.

A ledge 2| is formed at the meeting edges of the side walls l5 and I6 and the same is adapted to rest upon and engage the top 22 of the body element and to prevent the spout from being overforced into the opening H. A lifting lip 23 is formed integral with the side wall I 6 to facilitate opening the same.

Where my device is to be removably secured to the container and is to be placed upon other containers the same may be made as illustrated in Figs. 8 to 12 inclusive, and when so formed locking spring ears 24 and 25 of curved formation are formed from the body element and bent up to and made to engage the inner surfaces 28 and 21 of the side walls 9 and ID for gripping engagement with the walls of a container. Locking tongues 28 and 29 are formed in the locking ears 24 and 25.

The locking ears may be made as illustrated in Fig. 13 and when so made a lug 30 is formed integral with, and outwardly extends from both walls l5 and I6.

An offset 32 is formed integral with the locking ears 28 and 29 and the offset is placed in registry with the lug 30 so that as the pouring spout is fully closed the lug passes the offset with a spring action to maintain the spout in full lowered and locked position. A stop 33 is provided within the base of the pouring spout that prevents the disengagement of the spout with the slit l8.

While I have described and illustrated the container having one of my new and improved devices secured thereto at the point of filling of the container and having illustrated the container as having been filled through the open pouring spout, the carton may be filled with equal facility by the closing of the pouring spout and the filling of the container through the top of the container before the top is put into position.

While the form of mechanism and the method herein shown and described are admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment and the one method herein shown and described as it is susceptible of embodiment in various forms, and in methods all coming within the scope of the claims which follow.

What I claim is:
